Summary
The translationally controlled tumor protein (TCTP) is vital for cell functions and cancer therapy. Understanding its protein interactions, or interactome, is key to developing new cancer treatments.
Area of Science:
- Molecular Biology
- Cell Biology
- Oncology
Background:
- The translationally controlled tumor protein (TCTP) is an evolutionarily conserved, pleiotropic protein found in eukaryotes.
- TCTP regulates fundamental cellular processes including proliferation, apoptosis, and immune responses.
- Pioneering research identified TCTP's critical role in tumor reversion, highlighting its potential as a cancer therapeutic target.
Purpose of the Study:
- To consolidate current knowledge of the TCTP interactome.
- To provide a foundation for understanding TCTP's diverse cellular functions.
- To inform the rational design of TCTP-based therapeutic strategies.
Main Methods:
- Comprehensive review of protein interaction databases.
- Systematic literature search for identified TCTP interactions.
- Compilation and analysis of existing TCTP interactome data.
Main Results:
- TCTP's multifaceted actions are mediated through interactions with a network of proteins.
- These interactions regulate diverse physiological and pathological processes in a context-dependent manner.
- Existing data on TCTP interacting partners are largely from small-scale, system-specific studies.
Conclusions:
- A complete map of the TCTP interactome is essential for fully understanding its cellular roles.
- Further global profiling of TCTP interactions is needed.
- Elucidating the TCTP interactome will facilitate the development of novel cancer therapeutics.

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
